Bat is a mammal. You have the fold of skin from upper extremity to lower extremity to help in flying. You have very less effective way to fly as compared to hawks. In case of hawks you have upper extremity developed into powerful wings.
A human eyelid is not transparent of course. But some animals like snakes have permanently sealed transparent eyelids which protect their eyes from foreign materials. Frogs also have transparent eyelids to protect its eyes while swimming in water.
Vampire bats are real bats that drink blood. They cut a hole in an animal's skin and lap up the blood. They are not vampires, they're just bats.

no, it would not cause your eyes to be bloodshot. Bloodshot eyes come from inflammation of the conjunctiva (the mucus membranes over your eyes/eyelids). Thinning of the blood could not cause conjunctivitis (bloodshot eyes) unless you have an allergy to that medication that could cause bloodshot eyes (which I would think would be almost impossible).
